Disallow new For Side Effects (no-new)

The goal of using new with a constructor is typically to create an object of a particular type and store that object in a variable, such as:

varperson=newPerson();

It’s less common to use new and not store the result, such as:

newPerson();

In this case, the created object is thrown away because its reference isn’t stored anywhere, and in many cases, this means that the constructor should be replaced with a function that doesn’t require new to be used.

Rule Details

This rule is aimed at maintaining consistency and convention by disallowing constructor calls using the new keyword that do not assign the resulting object to a variable.
